U P D AT E D : 1 - 1 8 - 1 1RAM BLOWOUT PREVENTER TYPE 50(U) The Type 50 Blowout Preventer (BOP) is the most widely used blowout preventer in the world today. Its simple, compact design makes it well suited for subsea or surface drilling operations. The onepiece Type 50 Ram assembly provides a pressureenergized seal with maximum contact area to the drill pipe, casing, or tubing. This ensures a lower rubber pressure to the pipe and increased seal life. The oval ram and cavity design reduces stresses in the BOP body. Materials in contact with well fluids are resistant to hydrogen sulfide stress cracking per NACE Spec MR-0175. The Type 50 BOP operating system is designed to provide a fast and reliable closure of the well bore. Sealing is energized by well pressure acting on the ram and is maintained even with a loss of BOP operating pressure. Manual locking screws are provided as standard and hydraulic wedge locking devices are available for added safety. The Type 50 BOP operating system also controls the opening of the BOP for removal of the Ram Block assemblies. After removal of four Bonnet Bolts from either side of the BOP body the application of closing pressure separates the Bonnets from the body and exposes the ram assemblies. The well pressure is isolated from the operating system by a special combination of a resilient lip type seal, externally energized back up seal, and a vent port. This important feature ensures no leakage of the well fluids into the operating system. Special consideration in the design of the Type 50 BOP operating control system has been made for increased life and reliability. All moving surfaces are hard chrome or hardfaced for prolonged wear and pitting resistance. Bearing materials are also used to prevent metal-to-metal contact during ram closure and ram change operations. AXON Pressure Products only uses materials of the finest quality in the manufacture of the 50 BOP Every . component in the BOP is traceable back to its original mill test certificate.
